iMOW® RMI 422 robotic mower: fully automatic for the ideal lawn
General
Compact, capable and communicative. The STIHL RMI 422 PC iMOW® robotic mower combines features that make its operation particularly convenient. Equipped with the iiMOW® app*, you can view or organise the most important performance data anytime and anywhere. For example, the dynamic mowing plan can be tracked on the smartphone or tablet as well as the location of the automatic lawn mower – thanks to GPS localisation. Within the active times you defined, the smart robotic mower automatically picks the optimum mowing phases for the best possible cut using the rain sensor and a comparison with online weather services. The battery of the RMI 422 PC has a long life, which enables the iMow robotic mower to mow even medium-sized lawns of up to 1,700 m² reliable and with few breaks for charging. Not only does the robotic mower cut your lawn fully automatically, it also supplies it with nutrients at the same time. The iMOW® robotic mower cuts and shreds the grass in one step and returns it to the turf, where it acts as a biological fertiliser for a healthy lawn. If the terrain is uneven, the adaptive slope speed function adapts the propulsion on a gradient by up to 40%. If the iMOW® robotic mower encounters an obstacle when mowing, sensors in the movable hood detect the impact and the machine corrects its direction of travel. An installation kit is required for installation. The STIHL iMOW® robotic mowers comply with all applicable safety standards. Nevertheless, the iMOW® robotic mower is not a toy. During the iMOW® robotic mower's active times, in particular children, bystanders and animals must be kept out of the working area. Please refer to the operating instructions for further information. * The technical requirements for using the iMOW® app can be found at: https://web.imow.stihl.com/systems
